A memory device includes a mechanical element that exhibits distinct bistable states under amplitude modulation. The states are dynamically bistable or multi-stable with the application of a drive signal of a given frequency. The natural resonance of the element in conjunction with a hysteretic effect produces distinct states over a specific frequency range. Devices with multiple elements that respond to different frequency ranges provided on a common contact are formed with improved density. Th...

A bit cell of an organic memory is provided. The bit cell of the organic memory comprises an organic memory cell, a first transistor, a current mirror and a second transistor. To connect the organic memory cell to a data line, the first transistor is activated for reading and the second transistor is activated for writing. Furthermore, the first transistor has a greater size than the second transistor. Therefore, a fast processing time in writing and a large conduction current in reading are cat...

An active medium, typically a photochromic material and more typically spirbenzopyran, maintained in a three-dimensional matrix, typically of polymer, is illuminated in selected regions by two UV laser light beams, typically of 532 nm. and 1064 nm. wavelength, to change from a first, spiropyran, to a second, merocyanine, stable molecular isomeric form by process of two-photon absorption. Regions not temporally and spatially coincidently illuminated are unchanged. Later illumination of the select...
